The term “critical digital pedagogy” has been used to describe a broad range of approaches to teaching and learning rooted in critical theory, digital cultural studies, and the liberatory education promoted within schools of critical pedagogy since the 1960s. References to critical digital pedagogy began to appear in published scholarly literature in the early 2000s as a response to the expansion of neoliberal ideologies and policies in an age of proliferating digital and networked technologies. These shifts in technological, economic, and social organization have since become collectively described as the “platformization” of society, driven by processes such as datafication, commodification, and algorithmic selection. In response to concerns about the neoliberalization, dehumanization, and platformization of education specifically, the emergent field of critical digital pedagogy has coalesced into a community of educators, designers, and theorists with an international scope, though the majority of published scholarship originates from the United States and the European Union. While the approaches and methods that the proponents of critical digital pedagogy engage with are varied, three broad families of practice include critical instructional design, humanizing online teaching and learning, and digital ungrading. Following earlier traditions of critical pedagogy, practitioners in the field of critical digital pedagogy find themselves grappling with critiques of their approaches as overly politicized, ideologically driven, and pragmatically limited. Open issues in the field include the expanding role of machine learning and artificial intelligence, the role of political activism beyond the classroom, and the addressing of intersections between race, class, and other dimensions of identity within a critical framework.
